There are at least two bands named Traffic Jam
1) Status Quo was formed in 1962 under the name "The Scorpions". By 1967, the group had discovered psychedelia and named themselves Traffic, but were soon forced to change it to "Traffic Jam" to avoid confusion with Steve Winwood's Traffic, following an argument over who had registered the name first.
Formed in 1962 by Francis Rossi and Alan Lancaster at Sedgehill Comprehensive School, Catford, along with classmates Alan Key (drums) and Jess Jaworski (keyboards). Rossi and Lancaster played their first gig at the Samuel Jones Sports Club in Dulwich, London. In 1963, Key was replaced by John Coghlan and the band changed name to "The Spectres". They began writing their own material and after a year met Rick Parfitt who was playing with a cabaret band called The Highlights. By the end of 1965, Rossi and Parfitt, who had become close friends, made a commitment to continue working together. On 18 July 1966, The Spectres signed a five-year deal with Piccadilly Records, releasing two singles that year, "I (Who Have Nothing)" and "Hurdy Gurdy Man" (written by Alan Lancaster), and one the next year called "(We Ain't Got) Nothin' Yet" (a song originally recorded by New York psychedelic band The Blues Magoos). All three singles failed to make an impact on the charts. Parfitt joined the band in 1967.
